How can I create a function with random imputs? I have to create a function called tri_area that returns the area of a triangle with abse b and heigh h, where b and h are input arguments of the function in that order

function area = tri_area(b,h)
b=2
h=3
area=(b*h)/2;
end 
%They ask for ans answer when h=3 and b=2 AND OTHER with random inputs, and I down know how to do that

I think you may be confused. I believe what is asked is for a function with ARBITRARY inputs, in the sense it can be called with any arbitrary pair of numbers. I have often seen the word random used as was done, in a way that is perhaps confusing to some, when really all they intended was as a synonym of the word arbitrary.

function area = tri_area(b,h)
  area=(b*h)/2;
end

Don't assign values to b and h inside the function. PASS THEM IN. Now, use the function, as you wrote it.

>> area = tri_area(2,3)
area =
     3
     
>> area = tri_area(5,pi)
area =
          7.85398163397448
          
>> area = tri_area(5,sqrt(2))
area =
          3.53553390593274
          
>> area = tri_area(2.35,17.4545644)
area =
               20.50911317

As you see, it now works for any set of base and heights.

You don't want to re-set the values of those parameters passed in. That was your only problem.

Ohh thanks, now I can see my error I didn't understad the statement in that way

Now the script works well
